The new Toys R Us ad for December 6 has started arriving in mailboxes and one of the LEGO promotions that will be going on is for the LEGO Marvel Super Heroes Avengers Hulk (5003048) minifigure polybag. You can get it free with purchases of $30 or more on LEGO sets. LEGO Dimensions is excluded with this promotion. After the promo period is over, you can most likely purchase them separately probably for around $4.99 each, if there are any left over. The item code is 169132 if you have trouble finding them.
